First before starting my coursework i have decided to choose a factor that will affect the resistance of a wire i shall do this by going through all of the factors that affect the resistance of a wire and how i would measuring each factor to find out which would be the most effective and easiest factor to measure below is a list of. 1564 words - 6 pages gcse physics coursework - resistance of a wire coursework resistance of a wire task to investigate how the resistance of a wire is affected by the length of the wire theory what is resistance electricity is conducted through a conductor, in this case wire, by means of free electrons the number of. To the people taking their gcses in 2017, do you have all of the coursework titles i know: biology - factors that affect breathing rate physics - resistance in wires chemistry - if anyone knows the chemistry title for ocr 21st century a science then please say, because our school is going through it so. In the conduction of this experiment i will be examining the resistance of a wire this experiment queries the relation between voltage and amps flowing through 5 different thicknesses of wires electricity is transported through the wire by electrons when a circuit is switched off and there is no electric current present the.
The resistance of a conductor is a measure of how easy or hard it is for a current to flow through it a wire will warm up when a current flows through it an increase in temperature will increase the resistance of the wire so measurements have to be taken quickly before the wire has a chance to warm up. Mr habgood shows you how to measure the resistance of a wire when you change its length. Controlled assessment tasks for gcse physics require candidates to: • develop hypotheses circuit to collect data on current and voltage, and calculating the resistance of a wire (p4c) teachers may wish to teachers are advised to try out the experiment prior to candidates undertaking the task marking the controlled. An experiment to investigate the factors which affect resistance in a wirewhat is resistancea potential difference (v) applied across a wire of length (l), there is in the conductor, an electric field (e) in this electric field the free electrons are.
